head and tail

The head command prints the first n lines of a file. The -n flag specifies n as shown:

head -n 10 file1.txt

If you don't specify a number using the -n flag, it will default to 10.

The tail command prints the last n lines of a file. The -n flag specifies n as shown:

tail -n 10 file1.txt

Time to start investigating the bank's transactions.

1. Navigate into the worldbanc/private/transactions/ directory.

2. View the contents of the 2023.csv file with cat. You'll notice that it's a really long file.

3. Print the first 6 lines of the 2023.csv file.

   We print the first 6 lines because the first line in the file is the header, and we want to include that along with the first 5 transactions.

4. Print the last 5 lines of the 2023.csv file.

Submit the shell checks.
